Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot
TLDR
It is suggested that mountain uplift promotes species diversification across all elevational zones, and the majority of Andean orchid lineages only originated in the last 20–15 million yr.
Geographical structure, narrow species ranges, and Cenozoic diversification in a pantropical clade of epiphyllous leafy liverworts
TLDR
The clear geographic structure of the Leptolejeunea crown group points to evolutionary processes including rare long‐distance dispersal and subsequent speciation.

Rumbling Orchids: How To Assess Divergent Evolution Between Chloroplast Endosymbionts and the Nuclear Host.
TLDR
A pipeline is provided for executing PACo and ParaFit as well as displaying outlier associations in plots and trees by using the software R.The pipeline renders a method to identify outliers with high reliability and to assess the combinability of the independently derived data sets by means of statistical analyses.
A 3500-year-old leaf from a Pharaonic tomb reveals that New Kingdom Egyptians were cultivating domesticated watermelon
TLDR
It is shown that modern cultivars and the ancient plant uniquely share mutations in a lycopene metabolism gene (LYCB) affecting pulp color and a stop codon in a transcription factor regulating bitter cucurbitacin compounds, implying that the plant sequenced had red-fleshed and sweet fruits and that New Kingdom Egyptians were cultivating domesticated watermelons.
Plastid phylogenomics resolves ambiguous relationships within the orchid family and provides a solid timeframe for biogeography and macroevolution
TLDR
This study provides an expanded, robust temporal phylogenomic framework of the Orchidaceae that paves the way for biogeographical and macroevolutionary studies.
Random Tanglegram Partitions (Random TaPas): An Alexandrian Approach to the Cophylogenetic Gordian Knot
TLDR
This work presents a novel approach, Random Tanglegram Partitions (Random TaPas), that applies a given global-fit method to random partial tanglegrams of a fixed size to identify the associations, terminals and nodes that maximize phylogenetic congruence and suggests that the recursive partitioning of the tanglegram buffers the effect of phylogenetic nonindependence occurring in current global-fitting methods.
